Figure 3 Function classification and subcellular
localization analysis for differentially expressed proteins in P.
massoniana seedlings growing at various calcium levels. (A) Function
classification. (B) Subcellular localization predication.
These DEPs showed a wide subcellular localization and cellular component
distribution (Figure 3B), among which chloroplast (48.6%) and cytoplasm
(29.7%) were the dominant subcellular distribution compartments.
Mitochondria localized proteins and nucleus localized proteins accounted
for 4.0% and 4.0%, respectively. A small proportion of proteins were
predicted to localize to extracellular (1.4%), membrane (1.4%),
peroxisome (1.4%) or Golgi apparatus (1.4%). Besides, 8.1% proteins
had no definite subcellular localization distribution.
